Timber Lake, SD population, income and ZIP codes

Timber Lake city is a very small community in South Dakota, with 677 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #118 of 485 ranked by population — larger than 75% of them. The median age here is 27.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Timber Lake city earn a median of $58,000 a year, 26.2% below the national figure of $78,538 and 11% below the $65,500 median for the 79 South Dakota cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 18.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Timber Lake city is valued at $83,600, 72.4% below the national figure and 57% below the $192,800 peer median, while median gross rent runs $567 a month, 59.7% below the national figure, or roughly $6,804 across a full year. A household on the local median income would put about 11.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 1.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 60.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 27.4 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 677 residents, a handful of survey responses moves every median on this page. Compare Timber Lake city against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
